“Tenet” Physicist thoroughly examines! What was this “retrograde” world? *Spoiler alert [CINEMORE ACADEMY Vol.9]

` `Tenet '' directed by Christopher Nolan has been watched repeatedly since its release. The style that makes full use of the time axis is the same as always, but I think many people were surprised that this time it was more difficult than they expected.

It seems that some people are taking on the challenge of watching the movie two or three times and trying to understand the ``reverse world,'' and what is helping them do so is the theatrical pamphlet. The commentary provided by physicist Shiro Yamazaki is very easy to understand, and it is said that if you read the pamphlet thoroughly before watching the movie for the second time, you will be able to understand the movie much better. Professor Yamazaki also supervised the scientific subtitles for this film.

This time at CINEMORE ACADEMY, we will welcome Mr. Yamazaki as a guest and thoroughly examine the secret of the "reverse world" that Nolan has created from a physics perspective. Mr. Yamazaki spoke with Mr. Takayuki Oguchi, who has a reputation for explaining science fiction movies and has written articles on `` Interstellar '' and ` `2001: A Space Odyssey '' for CINEMORE.

To be honest, the two of them talked at such a high level that the editorial team who was present had some trouble keeping up with them, but the editorial team also asked us candid questions about things we had doubts about.

Kip Thorne, who won the Nobel Prize in Physics, participated in `` Tenet '' as a scientific researcher following `` Interstellar .'' What did Nolan create this time? ? I approached the world with spoilers in mind!

A movie that personifies elementary particles

Oguchi: My name is Takayuki Oguchi. I specialize in CG, VFX, and 3D images, and in the late 1980s I worked with the founder of IMAX to create videos for expositions. In this regard, I am grateful to director Christopher Nolan for continuing to use IMAX film.

There was also a time when I was thinking about turning the book ` `Black Holes and the Distortion of Space-Time into Einstein's Extraordinary Legacy'' by Kip Thorne, who served as executive producer and scientific consultant on `` Interstellar'' (2014), into a film. I'm grateful that Nolan made it.

For that reason, I was expecting ``Tenet'' to be a hard science fiction movie on par with ``Interstellar,'' but at first, all I noticed were the scientific inconsistencies, and to be honest, I was skeptical. . But then I started thinking, ``Maybe I should interpret this as a movie where the Feynman diagram is played out by humans.'' The thing that made the most sense to me was the phrase ``anthropomorphism of elementary particles,'' which Professor Yamazaki wrote in his pamphlet.

Yamazaki: I think you're absolutely right. When I saw this movie, the first thing I thought of was the Feynman diagram. Although I no longer specialize in this field, there was a time when I used Feynman diagrams to perform intensive theoretical calculations in fields such as quantum field theory, quantum electromagnetism , and quantum chromodynamics .

In fact, this is the case in the scene where there is a revolving door in a room painted red and a room painted blue. If you look at it from above, it's a diagram of electrons and positrons colliding and annihilating each other . For example, the red room is electronic. The blue room is a positron. The technical term for the intersection of these two is vertex, and it is truly a revolving door. The light that appears after that is omitted, so it's not exactly the same, but I thought it could be said to be a human-sized representation of what's happening in the ultra-microscopic world.

However, I would like to add that I don't necessarily know if Nolan uses that as a motif. After all, Nolan likes entropy and may be focusing on entropy.

What is entropy?
